2.Eurostars Air handler,air handling unit, ahu application
An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork

High efficiency filter
Air filtration is almost always present in order to provide clean dust-free air to the building occupants. It may be via simple low-MERV pleated media, HEPA, electrostatic, or a combination of techniques. Gas-phase and ultraviolet air treatments may be employed as well.

Filtration is typically placed first in the AHU in order to keep all the downstream components clean. Depending upon the grade of filtration required, typically filters will be arranged in two (or more) successive banks with a coarse-grade panel filter provided in front of a fine-grade bag filter, or other "final" filtration medium. The panel filter is cheaper to replace and maintain, and thus protects the more expensive bag filters.

The life of a filter may be assessed by monitoring the pressure drop through the filter medium at design air volume flow rate. This may be done by means of a visual display using a pressure gauge, or by a pressure switch linked to an alarm point on the building control system. Failure to replace a filter may eventually lead to its collapse, as the forces exerted upon it by the fan overcome its inherent strength, resulting in collapse and thus contamination of the air handler and downstream ductwork.

7.FAQ
Q:What are the differences between an air conditioner and an air handler?
Air handlers are an important part of your overall HVAC system, but they are not the complete air conditioning system.

An air handler is responsible for housing the equipment necessary to move air through your home or business. In most cases, it is located inside and operates both the heating and cooling systems. Air handlers look like a furnace, and are sometimes even mistaken for one. Air handlers can be made to work with a heat pump or air conditioner. It includes the indoor coil, which depending on the setting your system is running on, is used for both heating and cooling.

Air conditioning units include the condenser and are usually kept outside of your home or business.  Air conditioners actively pull heat out of the building through a variety of components configured together, and then this hot air is redirected outside. Throughout the process, air moves through the system via return ducts and over a refrigerant coil. Instead of adding cold air to the room, which is what it feels like, the system is actually just pulling hot air out and then recirculating the same air (without the heat) back into the building.
